Graduation woes

I have been trying to get through to the graduation department and I keep on getting passed from one person to the other. My email has not been responded too. It's honestly frustrating because the closing date for acceping the invite for the graduation is around the corner and yet no one is willing to help. Now I am forced to miss my graduation because I was placed on a 17H00 slot that is not working for me because I have a toddler that I can't leave with anyone on that time.
